GREASE-CUP.

Application filed January 26, 191e. Serial No. Sillf.

dispensing the grease to the parts tobelubricated, especially to the bearings, etc. of automobiles, flying machines, agricultural machines and other machines frequently subjected to hard shocks.

A further object of the invention is tok provide a grease-cup avoiding dental loss of the lubricant.

A still further object of the invention consists in the arrangement of retarding means arranged to yieldingly resist the rotary movement of the cover on the cup to prevent the top or cover of the grease-cup from accidentally working loose coming olf the cup while in use and to centraline the pin secured to the cup-cover or top for most economically, however yet ei'ect-ively dispensing the lubricant.

`rWith this end in view the cap or cover has secured thereto an inwardly extending three-faced pin adapted to be engaged by the ends of a peculiarly bent spring` located within the shank of the cup for yieldingl'y resisting the rotary movement of the cover on the cup by engaging at a time two of the faces of the pin.

The spring is exchangeably located in the upper part of the shank of said cup so that a broken or injured spring may easily and convenient-ly be exchanged for a new one.

Other objects of my invention will become apparent from the description and the accompanying drawing forming part of this specification, in which:

Figure 1 is a bottom plan view of the cap or cover illustrating the manner in which the three-edged pin is rmly secured thereto. Fig. 2 is a vertical sectional view of a grease" cup with my invention applied thereto. Fig. 3 is a top plan view of the grease cup proper showing the position of the spring therein in engagement with two faces of the pin. Fig. d is a front elevation of the grease-cup.

Similar letters of reference indicate correspending` parts in the figures.

Referring to the drawing, 10 represents the the acci- `inner wall of the circular bore 14 of said cup above said shoulder. The ends of the spring are peculiarly bent and extend inwardly at an angle 15 to each other with their upper free ends 16 forming the apex of said angle located vertically above the here 25, and in tight engagement with-each other. y' y Below the flange 11 the outer face of the cup-body is nut-shaped as at 17 for the engagement of a suitable tool, and a shank 18 with exterior threads is integrally made with said body and adapted to be suitably secured to the part of a machine to be lubricated.

The cap ortop 19 of the' grease-cup'l() is provided with an outer corrugated flange 2O near its upper end and an inner threaded wall 21 adapted to engage the outer thread of the upper fiange 11 of the cup 10. A three-cornered pin 22 is firmly embedded in the metal of the cover 23 of the top at the inner side thereof and its point of connection with said top is strengthened by a suitably shaped strengthening plate 24 or the like.

lt will be clear that when screwing the top 19 to the cup 10 the pointed three-edged pin will in the manner of a wedge engage two of the faces of the inner free ends of the i spring 13 and try to pry the same asunder so that these ends are frictionally engaging two of the faces of said vpin and offer a suitable resistance to the parts preventing the top from accidentally working loose and coming off the cup while in use. rlhis results also in preventing the accidental loss of any part of the lubricant and makes the device to a highly economical one.

The device operates as follows: The lubricating grease is forcibly pressed int-o the top or cap until the same is completely filled therewith, whereafter the cap is secured to the cup which will result in pressing the grease through the lower'opening 25 onto a bearing or other part to be O'reased.

It is to be understood that changes may be made in the size and shape of the single parts and general arrangement of my grease-cup without deviating from the spirit and scope of the present invention.
